Methods and algorithms of automatic increase for the quality (brightness and contrast) of weakly contrast 2D image, being formed by optic-electronic device on detecting of the dynamical object is proposed. Brightness increase is performed by summing at frequency region on wavelet-spectra of accumulated images at the short part of time for object detection. Summing image is restored by back (reverse) wavelet conversion. Wavelet spectra are sufficient statistics, calculated by the wavelet system built on the basis of wave prolate spheroidal function of zero order. Contrast increase is carried out by integral operator of differentiation. The offered algorithm is highly effective and realized at the real time scale on modem PC.
Keywords: optic-electronic apparatus, dynamic object, weak contrast 2D image, statistic rise of brighter, algorithm, criterion of efficiency.
